Hello dear steemians, this time I brought a pc to my house to do maintenance and change the hard drive that in this case was damaged, I decided to take some photos and make a publication about this, computer maintenance should be done regularly, although that it will also depend on the dirt in the environment, that is, if it is a closed environment with air conditioning and it is constantly kept clean the maintenance should be done every 6 months, now if the environment is open and a lot of dust enters the maintenance should be done every 3 months. I had the opportunity to maintain some equipment that really did not have any dirt, it was only necessary to replace the thermal paste and remove the little dust that had stored in the case, but I also did maintenance to a team that had it in an open environment in a hardware store and the team inside had everything from cement to cockroaches, something quite unpleasant. Well friends before we start doing the maintenance we must remove the static that we load in our body to avoid damaging some components that are sensitive to this type of energy such as RAM memories, can be done by touching a metal plate, they also sell some bracelets antistatic that are very useful, once done this proceed to remove the screws that hold the side cover of the case, remove it and find something like in the photo. **PHOTO 1** ![1.jpg](https://steemitimages.com/DQmdohZuCeqikfukHBJRBLpfyU1bGDEix3XKGnhytc4s479/1.jpg) Then we proceed to disconnect all cables from the motherboard, remove the screws from the Power Supply and remove it from the case, then remove the ram and video card that in this case has one, then remove the screws that hold the motherboard and we take it out of the case to do a better cleaning. I always used to uncover the source of power to make maintenance especially the fan that expels the hot air that this generates. **PHOTO 2** ![IMAGEN 2.png](https://steemitimages.com/DQmemdG4jYjk9J6nPfoWULeomDdZZ8AYn9ZxFEseyK3Cuz9/IMAGEN%202.png)

**PHOTO 6** ![9.jpg](https://steemitimages.com/DQmXMhKMQWcerqA43P3eBwfqr8quyHmrQHRh7cT3MQXM7X4/9.jpg) Proceed to assemble the equipment starting with the motherboard by placing the screws that hold it and connecting all the cables in the order in which they go, then place the power source and hold it with their respective screws, connect the 24-pin cable to the motherboard and the 4 pins of the processor, to ram memory I passed an eraser by the pins and then I cleaned it with a piece of white sheet, then I installed it and proceeded to test the equipment, also I mounted a hard drive new since the one I had was damaged, format the computer (I made a post of PC formatting) and voila, the equipment was already working at 100%. **PHOTO 7** ![12.jpg](https://steemitimages.com/DQmZCAT62VAn8ztU7msk5xTnoraMGBdH2Q2eTkRNYXvQuVY/12.jpg)
